Amputation, metatarsal, with toe, single
CPT4 code
Name of the Procedure:
Amputation, Metatarsal, with Toe, Single
Common Name(s): Partial Foot Amputation, Toe and Long Bone Removal
Medical Term: Metatarsal Ray Amputation
Summary
A metatarsal amputation with toe removal involves the surgical removal of one of the metatarsal bones and its associated toe. This procedure is typically done to address severe medical issues in the foot.
Purpose
Medical Condition or Problem:
This procedure is used to treat severe infections, gangrene, trauma, or conditions like diabetic foot ulcers that don't respond to other treatments.
Goals or Expected Outcomes:
The primary goal is to remove diseased or damaged tissue to prevent the spread of infection, promote healing, and preserve as much foot function as possible.
Indications
Specific Symptoms or Conditions:
- Severe infection or gangrene in the toe or foot
- Non-healing ulcers or wounds, especially in diabetic patients
- Severe foot trauma or injury
- Poor blood circulation leading to tissue death
Patient Criteria or Factors:
- Failure of conservative treatments like antibiotics or wound care
- Risk of spreading infection
- Pain and impaired functionality that diminish quality of life
Preparation
Pre-procedure Instructions:
- Fasting for at least 8 hours before surgery
- Adjustments in medications as advised by the doctor (e.g., blood thinners)
- Pre-surgical clearance tests like blood tests, ECG, and X-rays
- Consultation with anesthesiologist
Procedure Description
Step-by-step Explanation:
- Patient is positioned on the operating table.
- Anesthesia is administered to ensure the patient is pain-free.
- The surgeon makes an incision over the metatarsal bone and toe to be removed.
- Blood vessels are sealed to prevent excessive bleeding.
- The affected metatarsal bone along with the toe is surgically removed.
- The remaining tissue is reshaped and closed with sutures.
- A dressing is applied to protect the surgical site.
Tools and Equipment Used:
- Surgical scalpel
- Bone saw or cutting tool
- Electrocautery device for sealing blood vessels
Anesthesia:
General anesthesia or regional anesthesia (spinal or epidural), depending on the patient's condition.
Duration
Typically, the procedure takes about 1 to 2 hours.
Setting
Usually performed in a hospital operating room or a specialized surgical center.
Personnel
- Surgeon
- Surgical nurse
- Anesthesiologist/Anesthetist
- Surgical technician
Risks and Complications
Common Risks:
- Infection at the surgical site
- Excessive bleeding
- Blood clot formation
- Delayed wound healing
Rare Complications:
- Phantom pain (pain perceived in the amputated area)
- Neuroma (painful nerve tissue formation)
- Negative reaction to anesthesia
Management:
- Antibiotics for infection
- Pain management strategies
- Physical therapy for rehabilitation
Benefits
- Removal of infected or necrotic tissue
- Prevention of infection spread
- Potential for improved mobility and quality of life
- Pain relief from diseased tissue
Realization of Benefits:
Often immediate relief from the pain caused by the diseased tissue; full benefits may be realized after the healing and rehabilitation period.
Recovery
Post-procedure Care:
- Regular dressing changes and wound inspection
- Pain management with medications
- Physical therapy for rehabilitation
- Monitoring for signs of infection
Expected Recovery Time:
Typically 4 to 6 weeks, depending on the patient's overall health and healing capacity.
Restrictions:
- Limited weight-bearing activities as per the surgeon's advice
- Possible use of assistive devices (like crutches) initially
- Follow-up appointments for wound care and progress monitoring
Alternatives
Other Treatment Options:
- Antibiotic therapy alone (may be insufficient for severe cases)
- Local debridement (removing only the infected tissue without amputation)
- Revascularization procedures (if poor blood flow is the underlying cause)
Pros and Cons of Alternatives:
- Antibiotic Therapy: Less invasive but may not fully remove infected tissue.
- Local Debridement: Preserves foot structure but may need multiple procedures.
- Revascularization: Addresses blood flow issues but may not be suitable for all patients.
Patient Experience
During the Procedure:
Patients under general anesthesia will be unconscious and won't feel anything. Those with regional anesthesia will be awake but numb from the waist down.
After the Procedure:
Patients might experience discomfort, which can be managed with pain medications. The surgical site will need to be kept clean and dry. Physical therapy will be vital for recovery and regaining mobility.
